Chiles Research Institute, Robert W. Franz Cancer Center, Providence Portland Medical Center Here, we describe a high resolution whole-mount imaging method in the entire adult mouse ear skin, which enables us to visualize branching morphogenesis and patterning of peripheral nerves and blood vessels, as well as immune cell distribution.
